Here's more info on it:
http://www.eventid.net/display.asp?eventid=6702&eventno=294&source=DNS&phase=1

This can be due to a multihomed DNS server. If so, remove F&P and MS client
services and disable NetBIOS on the outer NIC and in DNS properties,
interface tab, only listen to the internal one.

If just one NIC, I've seen this disappear with using a forwarder (if not
already one configured).

Hope that helps.
